Description

The invention relates to the field of creating dynamic or static images and visual presentation of them in the form of drawings, texts, symbols and their combinations with image color change and can be used for street advertising, indoor advertising, interior decoration, architectural lighting of buildings and premises, signal information to obtain lighting effects of visually changing images.

The prior art method of presenting visual information with varying color intensity, including the application of a demonstration image with paints on a solid opaque surface of the carrier (shield) with the selection of tinting of individual fragments of the displayed image in accordance with the radiation wavelength of the light sources and its subsequent reproduction by external light flux with time-varying radiation wavelength in the visible frequency spectrum using a control device.

At the same time, the color of the light flux directed to the demonstration image is changed by switching the light sources with different filters. Filter change of light sources is carried out using automatic control devices.

The method has the following disadvantages:

1. It does not allow to obtain bright polychrome dynamically changing images due to the use of opaque media.

2. When illuminating a shield with an image as an external source of light flux, significant light losses occur due to scattering of the light flux.

3. From the shield, only one-sided demonstration of the image is possible.

4. Requires a complex design of the control system of the demonstration installation.

(RF patent №2124441, IPC 6 V 44 F 1/00, G 09 F 19/22. "A way of presenting visual information with changing color intensity." Priority from 08/07/97.)

There is also known a method of creating a pattern on a carrier, including applying to a previously prepared surface of a solid carrier of a pattern that completely or partially covers the surface of the carrier, and then lighting it with an external light source. The pattern is formed by applying several layers of various materials (paints or varnishes) to the carrier, each of which is optically transparent in its own wavelength range and forms a decorative effect when illuminated by radiation in a certain wavelength range.

The disadvantages of this method:

1. The method does not allow to obtain bright dynamically changing images, because its implementation is associated with significant light loss, and it is possible to obtain only a one-sided image from the surface of the medium.

2. The method is operable under external lighting by the light flux of the surface of the carrier.

3. The complexity and high cost of the method, because special sources of optical radiation (laser, pulsed), additional laser beam control devices are needed. (RF patent No. 2153989, IPC 7 V 44 F 1/00; G 0 9 F 13/00, 19/12 “Method for creating a drawing on a medium”. Priority from 08/09/99.)

The closest solution to the totality of the features of the claimed invention is a method of obtaining images in transparent objects by illumination with a light source from the end of each of the "n" transparent objects containing their own light-scattering pattern, mounted parallel to each other, and the corresponding number of light sources of one or different color, each light source independently illuminates its corresponding transparent object, and a light-scattering pattern applied to each of the "n" transparent objects can t be the same or different with respect to the rest of the drawings. The light sources are controlled by a controller with a predetermined algorithm that provides a different sequence and duration of the inclusion of light sources connected in parallel to the controller. In this case, the illumination of each transparent object can be single-frame or simultaneous.

The method has the following disadvantages:

1. It is possible to obtain a one-sided image in the transmitted light flux.

2. Use only solid, transparent media.

3. It is impossible to use for demonstration of images in large formats due to the cumbersome design with a set of "n" transparent hard and thick-walled media.

4. The inability to obtain clear and vivid images due to significant light scattering.

The invention solves the problem of obtaining bright, clear and dynamically changing mono-and polychromic demonstration images in any format, expanding the demonstration capabilities for both monochrome and polychrome images, as well as the choice of color gamut of the image.

The technical result obtained by using the invention is a cheaper way to simultaneously display images in transmitted and reflected light flux on the sides of the frame of any geometric shape of one installation, the use of film carriers for printing drawings and the ability to select their color gamut in the visible region of the light spectrum.

The inventive method of obtaining a demonstration image with a color change includes the formation of a composite of film media with printing on both sides of the first media of monochrome drawings and a polychrome pattern on an adjacent film carrier with perforation of at least 30% of its surface, the location between them of a tint film with light transmission 25-95 %, placement of a package of “n” such composites and internal sources of light flux in a frame also equipped with external light sources; integrated in one circuit with light sources, electronic devices are controlled by a controller with a given algorithm; reproduction of the image in the transmitted and reflected light flux is carried out simultaneously on any side of the frame of any geometric shape, changing the color of the displayed image by choosing the spectrum of light radiation for each picture.

The claimed invention differs from the prototype in that monochrome and polychrome patterns are applied onto parallel film carriers in a polygraphic manner, forming a composite from them, while one of the carriers is provided with perforation of at least 30% of its surface, a tint film is transmitted between the carriers, transmitting 25-95% of the light of a stream, a packet of “n” such composites is introduced into the frame with internal light sources located behind the composite, reproducing the image in the transmitted and reflected light flux simultaneously on the sides of the frame and any geometric shape, changing the color of the demonstration image by choosing the spectrum of light radiation for each picture.

The inventive method allows to obtain a bright, clear, color, dynamically changing demonstration image in the transmitted and reflected light flux in any format at the same time on the sides of the frame of any geometric shape.

The invention is illustrated in the drawing, which shows the implementation diagram of the inventive method of obtaining a demonstration image with a color change simultaneously on opposite sides of the frame (for example, 2 composites).

Each composite for image acquisition is formed as follows: monochrome drawings 2 are printed on both sides of the film carrier 1, the carrier 1 is fastened with a tinting film 3, a perforated film carrier 4 with a polychrome pattern 5 is fixed to them in parallel.

Sources of luminous flux 6 (incandescent, daylight, LEDs) and electronic devices 7 that control it, are placed behind the composite inside the frame 8, equipped with a composite tension device. Electronic devices 7, controlling the change in luminous flux 6, are combined in one circuit. All sources of the light flux are controlled by the controller 9 according to a predetermined algorithm. Outside the frame, light sources 10 are mounted.

Mirror the right composite form a composite on the left side of the frame 8.

When arranging “n” composites in the frame 8, on the left and right sides of the frame receive a demonstration image on two opposite sides of the frame at the same time. With a different geometric shape of the frame, composites and light sources are positioned similarly.

You can enter “n” composites from “n” drawings into the frame and obtain static or dynamic images.

When using several composites with different patterns applied and choosing the specified parts of the visible region of the spectrum, a dynamic image in transmitted and reflected light flux at any time of the day is obtained on almost any format and frame of any geometric shape, changing color in accordance with the algorithm specified by the controller.

In the daytime, in the absence of power supply, a polychromatic image is obtained on the internal sources of the light flux, and in the dark, using external light sources.

A monochrome image is obtained under illumination with a light flux of a certain wavelength of a pattern deposited on the internal carrier of the composite.

The above scheme for obtaining demonstration images with a color change of the claimed method confirms the possibility of simultaneous demonstration of the image in the transmitted and reflected light flux on the sides of one frame applied to film media in both monochrome and polychrome patterns.

The method allows you to expand the demonstration capabilities of the visual representation of images and expand the possibilities of using the proposed method in outdoor and indoor advertising, interior decoration, lighting of architectural ensembles, signal information, to obtain lighting effects of visually changing images on almost any frame format of any geometric shape.

With the unification of the design for the proposed method, the industrial development of this type of product will allow it to be relatively inexpensive with a completely new light image.
